In the critical field of life sciences research, the availability of high-quality reagents is paramount for obtaining accurate and reproducible results. Guanidine Thiocyanate (CAS 593-84-0) is a fundamental chemical compound, widely recognized for its indispensable role in nucleic acid extraction and other molecular biology applications. For scientists and procurement specialists, understanding how and where to source this essential reagent is crucial for the success of their projects.

Guanidine Thiocyanate is a powerful chaotropic salt, celebrated for its ability to denature proteins, including RNases and DNases. This denaturing action is vital for preserving the integrity of RNA and DNA during the lysis phase of extraction protocols. By effectively inactivating these nucleolytic enzymes, Guanidine Thiocyanate ensures that precious RNA and DNA samples remain intact for downstream analyses, such as gene expression studies, PCR, and sequencing. The typical specification for high-quality Guanidine Thiocyanate is an assay purity of 99.5% or higher, ensuring maximal efficacy and minimal interference with experimental procedures.

The primary application where Guanidine Thiocyanate shines is in RNA isolation. It is a key component in established methods like the acid guanidinium thiocyanate–phenol–chloroform extraction, which efficiently separates RNA from DNA and proteins. Its role in cell lysis and protein denaturation is central to achieving high yields of pure RNA. Consequently, researchers frequently search to buy Guanidine Thiocyanate to equip their laboratories for these essential tasks.

For those looking to secure a consistent and reliable supply, identifying a reputable Guanidine Thiocyanate manufacturer is key. Many leading chemical suppliers, including those based in China, offer high-purity Guanidine Thiocyanate at competitive prices. When evaluating potential suppliers, it is important to verify their quality control processes and request documentation such as a Certificate of Analysis (CoA) to confirm the product’s purity and specifications. Building a relationship with a dependable Guanidine Thiocyanate supplier ensures that your laboratory has uninterrupted access to this critical reagent.

In conclusion, Guanidine Thiocyanate is a non-negotiable reagent for many modern biological research endeavors. Prioritizing the purity and consistent quality of this compound, and sourcing it from trusted manufacturers and suppliers, is fundamental to achieving reliable and groundbreaking scientific results.
